We know the Universe is big. But just how big is it really? And how could we ever measure something as ephemeral as the cosmos? This new video by the ever-popular Minute Physics takes a stab at these issues — and not surprisingly, the answers are not as straightforward as we might hope.

As Minute Physics correctly points out, we first need to figure out what it is, exactly, that we're measuring. Given that we're hopelessly stuck in our Hubble Bubble, we can only see as far as the light reaching us allows. This gives us the impression that we're at the center of the Universe, but that can't possibly be right. So does anything lie beyond the observable Universe? And if so, for how long? Infinity?
